In the Aptio UEFI Firmware on my Windows 8.1 Asus Laptop, under Advanced Settings there’s a setting named ‘OS Selection’ and options are ‘Windows 8.x/Windows 7’.
I am trying to understand what’s the exact purpose of this setting and how it matters? There’s no info available within Firmware Help and nothing much is found online.
I did seek Asus support, but except for very basic & obvious explanation to set this as per intended OS there was no further explanation.
I though may be setting it to Windows 7 might be disabling Windows 8 exclusive features in the firmware like Fast Boot, Secure Boot etc but they are still totally independent.
Does anyone know how that setting really works? What different it does when set to Windows 7 and Windows 8.x?
Thanks.
